How do I convert each data value in a column matrix to log10 values

want column matrix of numbers converted to a column matrix of the log10 of the numbers

Is this a trick question? Something you're not telling us? to calculate the log10 of a matrix, you use the log10 function:

v = [10; 100; 2000];
log10(v)

Not a trick question jut not had to do this before. Very useful to be able to do this so efficiently to a column matrix of 1000 plus data points. Help much appreciated.

Most matlab functions can operate on the whole matrix at once. That's the whole point of matlab.
